cmake: detect SSL_set0_wbio in OpenSSL
Present in OpenSSL 1.1.0 and BoringSSL.
Missing from LibreSSL 3.8.0.

Follow-up to f39472ea9f

While here, also fix `RAND_egd()` detection which was broken, likely all
along. This feature is probably broken with CMake builds and also
requires a sufficiently obsolete OpenSSL version, so this part of the
update was not tested.

configure, cmake, lib: more form api deprecation
Introduce a --enable-form-api configure option to control its inclusion
in builds. The condition name defined for it is CURL_DISABLE_FORM_API.

Form api code is dependent of MIME: configure and CMake handle this
dependency automatically: CMake by making it a dependent option
explicitly, configure by inheriting the MIME value by default and
rejecting explicit incompatible values.

"form-api" is now a new hidden test feature.

Update libcurl modules to respect this option and adjust tests
accordingly.

cmake: support building static and shared libcurl in one go
This patch adds the ability to build a static and shared libcurl library
in a single build session. It also adds an option to select which one to
use when building the curl executable.

New build options:
- `BUILD_STATIC_LIBS`. Default: `OFF`.
  Enabled automatically if `BUILD_SHARED_LIBS` is `OFF`.
- `BUILD_STATIC_CURL`. Default: `OFF`.
  Requires `BUILD_STATIC_LIBS` enabled.
  Enabled automatically if building static libcurl only.
- `STATIC_LIB_SUFFIX`. Default: empty.
- `IMPORT_LIB_SUFFIX`. Default: `_imp` if implib filename would collide
  with static lib name (typically with MSVC) in Windows builds.
  Otherwise empty.

Also:

- Stop setting the `CURL_STATICLIB` macro via `curl_config.h`, and pass
  it directly to the compiler. This also allows to delete a condition
  from `tests/server/CMakeLists.txt`.

- Complete a TODO by following the logic used in autotools (also for
  `LIBCURL_NO_SHARED`), and set `-DCURL_STATICLIB` in `Cflags:` of
  `libcurl.pc` for _static-only_ curl builds.

- Convert an existing CI test to build both shared and static libcurl.

cmake: add support for "unity" builds
Aka "jumbo" or "amalgamation" builds. It means to compile all sources
per target as a single C source. This is experimental.

You can enable it by passing `-DCMAKE_UNITY_BUILD=ON` to cmake.
It requires CMake 3.16 or newer.

It makes builds (much) faster, allows for better optimizations and tends
to promote less ambiguous code.

Also add a new AppVeyor CI job and convert an existing one to use
"unity" mode (one MSVC, one MinGW), and enable it for one macOS CI job.

Fix related issues:
- add missing include guard to `easy_lock.h`.
- rename static variables and functions (and a macro) with names reused
  across sources, or shadowed by local variables.
- add an `#undef` after use.
- add a missing `#undef` before use.
- move internal definitions from `ftp.h` to `ftp.c`.
- `curl_memory.h` fixes to make it work when included repeatedly.
- stop building/linking curlx bits twice for a static-mode curl tool.
  These caused doubly defined symbols in unity builds.
- silence missing extern declarations compiler warning for ` _CRT_glob`.
- fix extern declarations for `tool_freq` and `tool_isVistaOrGreater`.
- fix colliding static symbols in debug mode: `debugtime()` and
  `statename`.
- rename `ssl_backend_data` structure to unique names for each
  TLS-backend, along with the `ssl_connect_data` struct member
  referencing them. This required adding casts for each access.
- add workaround for missing `[P]UNICODE_STRING` types in certain Windows
  builds when compiling `lib/ldap.c`. To support "unity" builds, we had
  to enable `SCHANNEL_USE_BLACKLISTS` for Schannel (a Windows
  `schannel.h` option) _globally_. This caused an indirect inclusion of
  Windows `schannel.h` from `ldap.c` via `winldap.h` to have it enabled
  as well. This requires `[P]UNICODE_STRING` types, which is apperantly
  not defined automatically (as seen with both MSVS and mingw-w64).
  This patch includes `<subauth.h>` to fix it.

- tweak unity builds to compile `lib/memdebug.c` separately in memory
  trace builds to avoid PP confusion.
- force-disable unity for test programs.
- do not compile and link libcurl sources to libtests _twice_ when libcurl
  is built in static mode.

KNOWN ISSUES:
- running tests with unity builds may fail in cases.
- some build configurations/env may not compile in unity mode. E.g.:

cmake: picky-linker fixes for openssl, ZLIB, H3 and more
- fix HTTP/3 support detection with OpenSSL/quictls built with ZLIB.
  (Requires curl be built with ZLIB option also.)

- fix HTTP/3 support detection with OpenSSL/quictls/LibreSSL and `ld`
  linker on Windows.

- fix HTTP/3 support detection with wolfSSL to automatically add
  `ws2_32` to the lib list on Windows. For all linkers.

- reposition ZLIB (and other compression) detection _after_ TLS
  detection, but before calling HTTP/3-support detection via
  `CheckQuicSupportInOpenSSL`.

  May be a regression from ebef55a61d
  May fix #10832 (Reported-by: Micah Snyder)

  This also seems to fix an odd case, where OpenSSL/quictls is correctly
  detected, but its header path is not set while compiling, breaking
  build at `src/curl_ntlm_core.c`. Reason for this remains undiscovered.

- satisfy "picky" linkers such as `ld` with MinGW, that are highly
  sensitive to lib order, by also adding brotli to the beginning of the
  lib list.

- satisfy "picky" linkers by adding certain Windows systems libs to
  the lib list for OpenSSL/LibreSSL. (Might need additional ones for
  other forks, such as `pthread` for BoringSSL.)

Note: It'd make sense to _always_ add `ws2_32`, `crypt32` (except
Windows App targets perhaps?), `bcrypt` (except old-mingw!) on Windows
at this point. They are almost always required, and if some aren't,
they are ignored by the linker with no effect on final binaries.

lib: sync guard for Curl_getaddrinfo_ex() definition and use
`Curl_getaddrinfo_ex()` gets _defined_ with `HAVE_GETADDRINFO` set. But,
`hostip4.c` _used_ it with `HAVE_GETADDRINFO_THREADSAFE` set alone. It
meant a build with the latter, but without the former flag could result
in calling this function but not defining it, and failing to link.

Patch this by adding an extra check for `HAVE_GETATTRINFO` around the
call.

Before this patch, build systems prevented this condition. Now they
don't need to.

While here, simplify the related CMake logic on Windows by setting
`HAVE_GETADDRINFO_THREADSAFE` to the detection result of
`HAVE_GETADDRINFO`. This expresses the following intent clearer than
the previous patch and keeps the logic in a single block of code:
When we have `getaddrinfo()` on Windows, it's always threadsafe.

tidy-up: process.h detection and use
This patch aims to cleanup the use of `process.h` header and the macro
`HAVE_PROCESS_H` associated with it.

- `process.h` is always available on Windows. In curl, it is required
  only for `_beginthreadex()` in `lib/curl_threads.c`.

- `process.h` is also available in MS-DOS. In curl, its only use was in
  `lib/smb.c` for `getpid()`. But `getpid()` is in fact declared by
  `unistd.h`, which is always enabled via `lib/config-dos.h`. So the
  header is not necessary.

- `HAVE_PROCESS_H` was detected by CMake, forced to 1 on Windows and
  left to real detection for other platforms.
  It was also set to always-on in `lib/config-win32.h` and
  `lib/config-dos.h`.
  In autotools builds, there was no detection and the macro was never
  set.

Based on these observations, in this patch we:

- Rework Windows `getpid` logic in `lib/smb.c` to always use the
  equivalent direct Win32 API function `GetCurrentProcessId()`, as we
  already did for Windows UWP apps. This makes `process.h` unnecessary
  here on Windows.

- Stop #including `process.h` into files where it was not necessary.
  This is everywhere, except `lib/curl_threads.c`.

  > Strangely enough, `lib/curl_threads.c` compiled fine with autotools
  > because `process.h` is also indirecty included via `unistd.h`. This
  > might have been broken in autotools MSVC builds, where the latter
  > header is missing.

- Delete all remaining `HAVE_PROCESS_H` feature guards, for they were
  unnecessary.

- Delete `HAVE_PROCESS_H` detection from CMake and predefined values
  from `lib/config-*.h` headers.

cmake: really enable warnings with clang
Even though `PICKY_COMPILER=ON` is the default, warnings were not
enabled when using llvm/clang, because `CMAKE_COMPILER_IS_CLANG` was
always false (in my tests at least).

This is the single use of this variable in curl, and in a different
place we already use `CMAKE_C_COMPILER_ID MATCHES "Clang"`, which works
as expected, so change the condition to use that instead.

Also fix the warnings uncovered by the above:

- lib: add casts to silence clang warnings

- schannel: add casts to silence clang warnings in ALPN code

  Assuming the code is correct, solve the warnings with a cast.
  This particular build case isn't CI tested.

  There is a chance the warning is relevant for some platforms, perhaps
  Windows 32-bit ARM7.

winidn: drop WANT_IDN_PROTOTYPES
`WANT_IDN_PROTOTYPES` was necessary to avoid using a header that came
via an optional package. MS stopped distributing this package some
years ago and the winidn definitions are part of standard headers (via
`windows.h`) since Vista.

Auto-detect Vista inside `lib/idn_win32.c` and enable the manual
definitions if building for an older Windows.

This allows to delete this manual knob from all build-systems.

Also drop the `_SAL_VERSION` sub-case:

Our manual definitions are now only enabled with old systems. We assume
that code analysis is not run on such systems, allowing us to delete the
SAL-friendly flavour of these.

cmake: set HAVE_SOCKADDR_IN6_SIN6_SCOPE_ID on Windows
`lib/config-win32.h` enables this configuration option unconditionally.
Make it apply to CMake builds as well.

While here, delete a broken check for
`HAVE_SOCKADDR_IN6_SIN6_SCOPE_ID` from `CMakeLists.txt`. This came with
the initial commit [1], but did not include the actual verification code
inside `CMake/CurlTests.c`, so it always failed. A later commit [2]
added a second test, for non-Windows platforms.

Enabling this flag causes test 1056 to fail with CMake builds, as they
do with autotools builds. Let's apply the same solution and ignore the
results here as well.

- Builds targeting Windows 2000 and earlier
- MS Visual C++ 5.0 (1997) and earlier

Also make sure to disable this feature when `HAVE_GETADDRINFO` isn't
set, to avoid a broken build. We might want to handle that in the C

cmake: sync HAVE_SIGNAL detection with autotools
`HAVE_SIGNAL` means the availability of the `signal()` function in
autotools, while in CMake it meant the availability of that function
_and_ the symbol `SIGALRM`.

The latter is not available on Windows, but the function is, which means
on Windows, autotools did define `HAVE_SIGNAL`, but CMake did not,
introducing a slight difference into the binaries.

This patch syncs CMake behaviour with autotools to look for the function
only.

The logic came with the initial commit adding CMake support to curl, so
the commit history doesn't reveal the reason behind it. In any case,
it's best to check the existence of `SIGALRM` directly in the source
before use. For now, curl builds fine with `HAVE_SIGNAL` enabled and
`SIGALRM` missing.

The custom check was also non-portable, so this patch deletes it in

cmake: enable more detection on Windows
Enable `HAVE_UNISTD_H`, `HAVE_STRTOK_R` and `HAVE_STRCASECMP` detection
on Windows, instead of having predefined values.

With these features detected correctly, CMake Windows builds get closer
to the autotools and `config-win32.h` ones.

This also fixes detecting `HAVE_FTRUNCATE` correctly, which required
`unistd.h`.

Fixing `ftruncate()` in turn causes a build warning/error with legacy
MinGW/MSYS1 due to an offset type size mismatch. This env misses to
detect `HAVE_FILE_OFFSET_BITS`, which may be a reason. This patch
force-disables `HAVE_FTRUNCATE` for this platform.

tidy-up: delete parallel/unused feature flags
Detecting headers and lib separately makes sense when headers come in
variations or with extra ones, but this wasn't the case here. These were
duplicate/parallel macros that we had to keep in sync with each other
for a working build. This patch leaves a single macro for each of these
dependencies:

- Rely on `HAVE_LIBZ`, delete parallel `HAVE_ZLIB_H`.

  Also delete CMake logic making sure these two were in sync, along with
  a toggle to turn off that logic, called `CURL_SPECIAL_LIBZ`.

  Also delete stray `HAVE_ZLIB` defines.

  There is also a `USE_ZLIB` variant in `lib/config-dos.h`. This patch
  retains it for compatibility and deprecates it.

- Rely on `USE_LIBSSH2`, delete parallel `HAVE_LIBSSH2_H`.

  Also delete `LIBSSH2_WIN32`, `LIBSSH2_LIBRARY` from
  `winbuild/MakefileBuild.vc`, these have a role when building libssh2
  itself. And `CURL_USE_LIBSSH`, which had no use at all.

  Also delete stray `HAVE_LIBSSH2` defines.

- Rely on `USE_LIBSSH`, delete parallel `HAVE_LIBSSH_LIBSSH_H`.

  Also delete `LIBSSH_WIN32`, `LIBSSH_LIBRARY` and `HAVE_LIBSSH` from
  `winbuild/MakefileBuild.vc`, these were the result of copy-pasting the
  libssh2 line, and were not having any use.

- Delete unused `HAVE_LIBPSL_H` and `HAVE_LIBPSL`.
